URBNFit Small Exercise Ball - 9-inch Mini Pilates Ball with Fitness Guide for Yoga, Barre, Physical Therapy, Stretching & Core Stability Workout

Good spiked ball that I use for Mat Pilates. Stays in place

It's easy to inflate and get the plug in. I use it for physical therapy for my knee replacement and it's worked beautifully.

Just what I was looking for. Works great at my chair yoga class

This exercise ball is great for at home Pilates! I was looking for a ball that is much smaller and lighter when it comes to doing strength training. It was easy to pump up and fast. My only main concern is that it deflated very quickly and I had to always re-pump it back up every week.

I like the material, the durability, size and there was no yucky smell. I found it super easy to blow up, took me less than a minute and it came with extra plugs which is nice. I like that it's black and now I can start doing the ab exercises that were too hard for me without some support. It's comfortable and cushy and I also like using it as a neck pillow when I'm laying on the floor doing stretches on my half foam roller and whatnot. So glad I snatched this up on sale.

Waste of money. Very disappointing. Will be returning if possible. I am not sure how this product ever got any good reviews. As many other reviews mention, this ball doesn't retain air! This is mainly because it's hard to put the plastic stopper in place in time to trap the air. I tried blowing it up with my own lung power and with an electric air pump - both times I could get the ball to an appropriate firmess, but it would immediately deflate significantly no matter how quickly I put the plastic stopper in place. The air hole needs to have some sort of valve in place to create a better seal and trap escaping air. It also was unclear how firm the ball should really be when fully inflated. Some of the illustrations enclosed showed the ball as an oval when performing exercises - presumably under the weight of the person - but I was seeking a firm ball like a normal semi-rigid yoga ball that would maintain a circle - for rounded support with weight on it. This ball doesn't seem capable of that, it becomes oval and misshapen quickly. It also deflated completely when left for 8 hours so it would need to be blown up each time it is used. The description says it can support 600 lbs, but I didn't dare put even my full 140 lbs on it, because it seemed like the plastic stopper would pop out with any pressure and instantly deflate and cause injury to anyone applying weight to it. Horrible product.

My previous Theraband Mini Ball met an untimely end thanks to my dog, which led me to try this alternative. I actually prefer this new brand significantly. The ball's superior, smoother texture offers a much more supportive experience, particularly during core workouts. Very durable.

I bought this to use with my Beachbody workouts. I found it difficult to inflate because I had to prop the ball on the counter while I blew into the straw and then you have to be SUPER QUICK to get your finger over the hole once you pull the straw out and then even QUICKER to jam the plastic plug into the hole, otherwise this tiny ball is completely deflated and you have to start all over (I'm talking from experience here...tried several times unsuccessfully to inflate the ball before figuring out this method 😳)... But even once inflated, after using it only a handful of times, it's not holding air... Not sure if there's a pinhole somewhere or the plug isn't airtight... The attached pic shows the ball a few days after it was fully inflated...and I was on vacation and didn't even use it during that timeI guess you get what you pay for
